Socketed Microprocessor
The 478-pin, socketed Intel® Pentium® 4 microprocessor, shown above with the heat sink and fan attached, contains an integrated 8-KB primary (L1) cache
with a secondary (L2) 256-KB Advanced Transfer Cache that resides in the processor's core and runs at the processor's internal clock speed.
The socketed microprocessor inserts into the ZIF connector mounted on the system board . A clip secures the heat sink to the connector.
